I've grown and tasted about 4,000 plus varieties and about the only one,for me,that has a unique taste is Prue. Actually the aroma of cut fruits gives it away before I even taste it.
Whether or not a variety has a unique taste is not just in the mouth of the taster alone, but also how a person grows their tomatoes,what amendments they use and when,if any, and also the weather in any one season,etc.
So I can't see any consensus on unique tastes with tomatoes.
And it's also good to know that there are human genes related to what tastes we can taste,not all the same for all folks, and that's an additional complication to this subject and a very important one IMO.
I'm having seedlings for 17 varieties being raised for me to be grown here at home for me by someone else since with this walker I can no longer do any outside work, most not known to others and I'll try to let you know if I can add any of them to my Prue one.
